Referring to fig. 1 to 5, a fuel filler pipe assembly according to an embodiment of the present invention includes a fuel filler pipe 200, an oil vapor recovery assembly 300, and a vent pipe 400. The oil gas recovery assembly 300 includes a driving impeller 310, a rotating shaft 320, a recovery impeller 330, and a housing 340. An oil passage 512 is formed in the housing 340, and the housing 340 is further provided with a first oil inlet 513 and a first oil outlet 511 which are communicated with the oil passage 512. A ventilation channel 514 is formed in the casing 340, and the casing 340 is further provided with an air inlet 516 and an air outlet 515 which are communicated with the ventilation channel 514. The drive impeller 310 is located in the oil passage 512 and the recovery impeller 330 is located in the vent passage 514. The rotating shaft 320 is rotatably connected to the housing 340, a driving impeller 310 is fixed to one end of the rotating shaft 320, and a recovery impeller 330 is fixed to the other end of the rotating shaft 320.
